Syntax options:

       PROTOTYPES[=prototypesfile]
       NOPROTOTYPES

    The PROTOTYPES qualifier uses the LANGUAGE clause from the module
    to generate routine declarations for the following languages: C
    (C++), Pascal, and BLISS. The qualifier is ignored for all other
    language values.

    The prototypes file specification defaults to the same device,
    directory, and file name as the module language source. The file
    types default to .h for C, .PAS for Pascal, and .REQ for BLISS.

    For the BLISS language, the PROTOTYPES qualifier generates
    EXTERNAL ROUTINE declarations for each SQL module language
    procedure.

    For the Pascal language, the generated external procedure
    declarations are suitable for inclusion in either a Pascal
    program or module. Structured types (RECORD ... END RECORD),
    SQLDA, and SQLCA used by the SQL module language procedures are
    declared as UNSAFE arrays of bytes to simplify passing structures
    via these external definitions. However, care must be taken as
    this form of declaration disables the strong typing checks in
    Pascal.

    The output for the C language includes pre-processor directives
    to conditionally include C++ "extern C" syntax and also allow
    multiple #include references.

    The default setting is NOPROTOTYPES.
